SPECIFICATION forming part of Letters Patent No. 554,932, dated February18, 1896.

Application filed Augu t 12,1895- Serial No. 559,056. (No model.)

To (LZZ whom it may concern.-

Be it known that I, HEINRICH WILHELM FRIEDRICH JAEGER, of Sandusky, inthe county of Erie'and State of Ohio, have invented a new and ImprovedOar-Door, of which the following is a full, clear, and exactdescription.

The object of this invention is to provide a car-door which will be moredurable and simple in construction than others heretofore produced andalso which will ride more easily on its bearings.

To this end the invention consists in various combinations of parts andfeatures of construction, which will be fully described here inafter,and finally embodied in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a side elevation of a portion of a freight-carequipped with my improvements. Fig. 2 is a similar view showing theparts in a different position. Fig. 3 is a vertical longitudinal sectionof the car, showing an interior view of the door. Fig.4 is a horizontal.section on the line 4 4 of Fig. 3. Fig. 5 is a vertical section on theline 5 5 of Fig. 3. Fig. 6 is a fragmentary view showing the rollers orcasters for mounting the door. Fig. 7 is a sectional view of the sameparts, taken on the line 7 7 of Fig. 6; and Fig. 8 is also a sectionalview of these parts on the line 8 8 of Fig. 7.

The car-body 1 is provided with the usual opening having the posts 2 ateither side thereof, and these posts have the sides of the car securedto them and are braced by outwardly-extending braces 3. Lying alongsidethe inner sides of the car are the beams 4 and 5, the beam 4 beingprovided with a vertical dovetail 6, which is locked with the adjacentpost 2, and the beams 5 being provided with a horizontal dovetail 7, thesame being also locked with the adjacent post.

Pivotally mounted on a pin 8 is a grain-door 9, the same being arrangedto fit in grooves 10, formed in the respective posts 2, and thesegrooves are aligned with the groove 11, formed in the beams 4 at theright of the door and in the adjacent brace 3. This groove 11 is provided to receive the door 9 when the same is open, as shown in dottedlines in Fig. 3.

Fixed to the inner side of the car is a chain 12, provided with a hook13, and this is adapted to engage with an opening 14, formed in thegrain-door 9, whereby the same may be held in an open position, as shownin dotted lines in Fig. 3. The upper right-hand corner of the grain-dooris provided with an opening 15, (see dotted lines in Fig. 3,) throughwhich a pin 16 is adapted to pass, whereby the graindoor may be lockedin a closed position, and this pin 16 is provided with a chain, the samebeing secured to the outer side of the car and serving to prevent theloss of the pin.

The door 9 fits snugly within its respective grooves 10, as will beunderstood, to prevent the escape of grain which may be carried in thecar, and the door-frame is provided at the bottom of the door-openingwith a tread 17 the same being securely seated upon the floor of the carand formed with a groove receiving the lower edge of the grain-door,which construction serves to further tighten the connection of the doorwith the other parts of the car.

The outer or door proper of the car comprises a suitable body structure18, provided at its inner side with a roller 19, which projects beyondthe inner side of the door and which is held in a frame 20. This rolleris adapted to travel along a wear-plate 21, secured to the outer side ofthe car, and by means of the roller 19 and the plate 21 the frictionwhich would otherwise exist between the body of the car and the door 18is overcome. The outward movement of the door is limited by means of thestop 22, which is secured to the side of the car, as best shown in Figs,1 and 2.

Supported at the lower edge of the dooropening in the sides of the carand extending beyond the left-hand side of said opening is a foot-track23, the same being held in place by means of brackets 24 secured to theside of the car, and this foot-track 23 is provided with a verticalflange at its outer edge and has the rollers or casters 25 of the door18 mounted thereon. These rollers or casters 25 are carried in housings26, each of the same comprising two parts a and b, the parts a beingprovided with a horizontally-extending plate 0, which passes through theupper part of a recess formed in the bottom of the car-door, and whichis projected through an opening cl formed in the section 1), bolts 27being provided and passed through the two sections and through thedoor,by which means the said sections are held in place. The rollers orcasters are preferably two in numher, and are, together with theirrespective housings 26, duplicates in construction.

Located above the doonopening is the headtrack 28, which is rigidlysecured in place and which is provided with a downwardly-extending outerflange. This track 28 has the rollers or casters 29 engaged therewith,and the said rollers are each mounted in a U-shaped housing 30, each ofwhich is provided with a bow-spring 31, located and secured to its underside, and the said bow-sprin g 31 is in turn engaged with a secondhousing 30, which receives the housing 26 and the greater portion of theroller or caster, and this housing is formed with vertical slots 33, onein each side, which slots receive the trunnions 34 of the rollers orcasters. The housings 32 are each rigidly secured in recesses formed inthe upper edge of the body portion of the door, and by means of thesprings 31 the respective housings are yieldingly mounted in the largerhousings, so that the rollers or casters will be spring-pressed againstthe track 28. The housings 32 are similar in construction to thehousings 26 above described, and comprise two sections 0 and f boltedone on each side of the door, the section 6 having a horizontal ortransverse plate 9, which projects into an opening h formed in the othersection. By these means it will be seen that the door 18 is mounted soas to be capable of sliding laterally alongside of the car, and thatthis sliding movement may be eitected without the presence of more thana nominal degree of friction. It will also be seen that the springs 31will press the respective rollers or casters 29 into yielding engagementwith the track 28 and by these means all jarring and rattling of allmovable parts are prevented and the life of said parts is lengthened.

The right-hand post 2 is extended outwardly beyond the side of the carand provided with vertically-aligned eyes 34-, between which the hasp 35is pivotally mounted, and this hasp swings 011 a vertical axis and isprovided with a slot 36, receiving the keeper 37 of the wearplate 38,and also with an inwardly-projecting lip 39, which is received in acorresponding depression of the said wear-plate 38. The wear-plate 88 isrigidly secured to the side of the car-door 18 and provided with aswinging lock-pin 41, the same being curved so as to pass through theeye 37 and to lock the hasp 35 in place. By these means the door 18 maybe secured in a closed position. Through the medium of the projectinglip 39 and the recess 40 the hasp 35 and the plate 38 are more securelyconnected, and the eye 37 is relieved of strain which would otherwise beimposed thereon.

From the foregoing description it will be seen that I have provided adoor which may be operated without more than nominal physical exertionon the part of the operator, and that this is due to the reduction ofthe friction between the parts, and it will also be seen that owing tothe peculiar construction of the rollers or casters loose movement orplay of the movable parts is prevented and their life consequentlylengthened. The operation of the door is similar to that of othercar-doors and needs no special description.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. The combination with a car having an opening inthe side thereof, of a door, tracks mounted above and below the opening,a roller at one edge of the door and engaging one track, a stationaryhousing at the opposite edge of the door and having slots therein, amovable housing within the stationary housing, a spring engaging themovable housing and a roller mounted in the movable housing and havingits trunnions slidable in the slots of the stationaryhousing,substantiallyas described.
